Wierdest ones... alright, why not.

Hairdressing/touching someone's hair, or having someone doing that to me.
Applying make-up/paint to someone, or having someone doing that to me2.
People eating, specially if it's something made by me. *necessary lol here*
People saying certain words... certain words.
I have super fetishes for some type of clothes but i guess that it's kinda acceptable, the less probable ones are hakamas, turtlenecks, v-necks (with no undershirt) and kneepads.. but i just almost have an anti-fetish for nude people, so i guess that that is the weird thing.
Body parts such as backs, sternocleidomastoid mucles yo, clavicles, Adam's apple, maybearmpitswhoknowsshutup, and... legs and feet are too mainstream for this thread, maybe.

Futa with female when the futa appears to be more sensitive.
Females/futanari with their external and internal parts stimulated. (not weird, but it usually seems to be one or the other)
Wrestling with the objective of making your opponent climax first.

Inter...national?

Mutual cannibalism

Cosmic horror sex

Also I'm really happy Mangagamer will translate Maggot Baits

Damn I'm surprised at how popular mutal cannibalism seems to have gotten.

I'm a simple man, I still prefer a good old fashioned "murder the girl, then eat her" in my guro.

Oppai loli ._.

As an alternative for pregnancy, my favorite kink is actually having long tongues or tentacles actually push deep into my character's womb and transmit a type of signal that tricks my character's ovaries into believing that it is time to release an egg. The appendage, whatever it is, then opens itself, and extracts the egg from my character through itself, whether for food, or to use for its own purposes.

Glad I'm not the only one.
I'd like a 6 pack of Mcfucknuggets with a side of cock please (my cock).

Guys, pls. Slow down a bit, there.
